Virtual agent communication for electronic device

ABSTRACT

Methods and apparatus for communicating between virtual agents associated with users of electronic devices connected via at least one network. A first user may instruct an associated first virtual agent to invoke a communication session with a second virtual agent associated with a second user. To invoke the communication session, the first virtual agent may send an outgoing communication to the second virtual agent and the outgoing communication may instruct the second virtual agent to perform at least one action on behalf of the first user. Virtual agents associated with different users may alternatively communicate with each other in the absence of user interaction to perform a collaborative action.

BACKGROUND

In recent years, electronic devices such as smartphones and tabletcomputers often include applications known as virtual agents or virtualassistants that assist users in performing functions such as searchingfor content on a network (e.g., the Internet) and interacting with otherapplications. Users can interact with a virtual agent using typing ortouch to perform these functions. Additionally, some devices include aspeech interface to enable users to interact with a virtual agent usingspeech input. These virtual agents are generally platform specific andwork with devices that use a particular operating system. For example,the Siri® assistant available from Apple Computers, Inc. is configuredto work with devices running the iOS mobile operating system, and theEVA assistant available from Bulletproof Corp. is configured to workwith devices running the Android mobile operating system available fromGoogle, Inc.

DETAILED DESCRIPTION

The inventors have recognized and appreciated that although conventionalvirtual agents are useful for assisting users with various tasks such asinitiating a call or searching for content on the world wide web, thefunctionality of a conventional virtual agent may be improved byenabling a virtual agent associated with one user to interact withvirtual agents associated with other users to perform collaborativeactions such as finding another user's location, scheduling a meetingwith another user, and sharing contact information or other data amongusers. To this end, some embodiments of the invention are directed atimproving the functionality of a virtual agent by enablingagent-to-agent communication to perform one or more actions.

An exemplary system 100 for use in accordance with some embodiments ofthe invention is illustrated in FIG. 1. System 100 includes electronicdevice 102, which may be implemented as, but is not limited to, a cellphone, a smartphone, a tablet computer, and a laptop computer. System100 may include any number of electronic devices. For example, system100 also includes cell phone 130 and tablet computer 140. Althoughvarious components of electronic device 102 are described below, itshould be appreciated that other devices in system 100 including cellphone 130 and/or tablet computer 140 may include at least somecomponents that are similar these described in connection withelectronic device 102.

Electronic device 102 may be configured to receive input from a user toperform one or more functions. To receive user input, electronic device102 may include input interface 104 including, but not limited to, akeyboard interface (e.g., a QWERTY keyboard), a touchscreen interface,and a speech interface such as a microphone. In embodiments that includea speech interface, the received speech input may be sent to anautomatic speech recognition (ASR) engine (not shown) to recognize thecontent of the received speech input. The ASR engine may be included asa portion of electronic device 102 and/or the ASR engine may be locatedremotely from electronic device 102 and may be in communication withelectronic device 102 using any suitable communication mediums (e.g.,one or more networks). In some embodiments, electronic device 102 may beassociated with one or more local ASR engines and one or more remotelylocated ASR engines, whereby at least some received speech input isprocessed by the one or more local ASR engine(s) and at least somereceived speech input is processed by the one or more remotely-locatedASR engines. Examples of such distributed ASR systems are known by thoseof skill in the art. Speech input sent to the one or more remote ASRengine(s) for recognition using one or more communication medium(s)(e.g., one or more networks) connecting the electronic device 102 andthe ASR engine(s) may be returned to the electronic device 102 from theremotely-located ASR engine(s) using the same or different communicationmedium(s).

In some embodiments, the ASR engine(s) may be configured to recognizespeech input using one or more fixed or dynamically-generated grammarsand/or vocabularies. Alternatively, some embodiments may allow free-forminput to enable the user to speak to the virtual agent in a more naturalway and the ASR engine may recognize whatever the user is saying using,for example, a natural language understanding (NLU) model. Inembodiments that include speech recognition based on an NLU model, thevirtual agent may attempt to infer an action the user wants to performbased on the NLU result. It should be appreciated that the particularmanner in which recognition of speech input is implemented does notlimit embodiments of the invention as any suitable speech recognitionimplementation may be used.

Electronic device 102 also includes a user interface 106 to enable theuser to interact with the device to perform various actions. Forexample, in some embodiments, user interface 106 may display a pluralityof icons associated with a plurality of applications and the user mayinteract with one or more of the icons to launch the associatedapplication. Any suitable user interface may be used as embodiments ofthe invention are not limited in this respect.

Electronic device 102 may include one or more applications 108configured to execute on the device. Some applications may be localapplications that execute primarily on the electronic device 102. Forexample, a scheduling application (e.g., calendar application) mayexecute on the electronic device to enable the user to store schedulinginformation about events and/or appointments. Data associated with suchapplications may be stored locally on electronic device or at least aportion of the data may be stored remotely, as discussed in more detailbelow. Other applications (e.g., web-based applications) may beconfigured to interact with one or more computers over one or morenetworks. For example, a web-based email application may be hosted byone or more web servers such that when a user wants to check email usingthe email application, a request will be sent from the electronic deviceto one or more remotely-located servers that host the email application.

In some embodiments, electronic device 102 may include a location sensor110 configured to determine the location of the electronic device. Forexample, the location sensor may be a global positioning system (GPS)sensor configured to determine coordinates for the location of thedevice. Some embodiments may include an application that interacts withlocation sensor 110 to display the location of the electronic device 102on a map. Location sensor 110 may be implemented in any suitable way andembodiments of the invention are not limited in this respect.

As discussed briefly above, electronic device 102 may store user data112, which describes information that is specific to a particular useror electronic device. For example, user data 112 may include, but is notlimited to, contact information, calendar information, user preferencesinformation, behavioral history information, and location information.In some embodiments, user data 112 may also include media contentinformation such as music or picture data associate with a particularuser account or device. In some embodiments, at least some user data 112may be stored remote from electronic device 102 in a location that isaccessible to electronic device 102 via at least one network. Forexample, at least some user data 112 may be stored in network storage150 accessible to electronic device 102 via network 160. Data storedremote from an electronic device is commonly referred to as data stored“in the cloud” and such data is often accessible from multiple devicesby the same user. The particular manner in which user data 112 is storedis not a limiting aspect of embodiments of the invention as the userdata 112 may be stored in any suitable location accessible to electronicdevice 102.

Electronic device 102 also includes communication interface 120configured to send and receive communications to and from otherelectronic devices (e.g., cell phone 130 and tablet computer 140) andnetwork storage 150 via network 160. Communications may be sent vianetwork 160 using any suitable protocol and any suitable message formatas embodiments of the invention are not limited by the particularnetwork implementation details that are employed.

In some embodiments, electronic device 102 also includes virtual agent114. A user can interact with virtual agent 114 to perform a range offunctions such as controlling the electronic device (e.g., sendingmessages, placing calls, opening applications) or accessing content andapplications (e.g., web searching, posting information on a website). Insome embodiments, virtual agent 114 may be implemented as an applicationwhich communicates with other applications 108 and user data 112 toperform the functions described above, and other functions as describedin more detail below. Not all devices in system 100 may be associatedwith virtual agents and embodiments of the invention are not limited inthis respect. As discussed in further detail below, electronic devicesthat are not associated with virtual agents may receive communicationsin a conventional format (e.g., text messages, email, telephone calls,etc.), whereas electronic devices associated with virtual agents may becapable of taking advantage of increased communication functionality andan enhanced user experience in accordance with some embodiments of theinvention.

A virtual agent may be associated with a particular user and/or devicein any suitable way. In some embodiments, a virtual agent may be anapplication executing on a user's electronic device, as described above.In such embodiments, the virtual agent is associated with the user ofthe device on which the virtual agent is installed. In otherembodiments, a virtual agent may not be installed on a user's electronicdevice, but may execute primarily on a computer at a remotely-locatedlocation accessible to the user's electronic device via one or morenetworks. In embodiments where the virtual agent is located remotelyfrom the user's electronic device, the virtual agent may include atleast one identifier identifying one or more electronic devicesassociated with the user and/or at least one identifier identifying theuser. Based on these one or more identifiers, the virtual agent may beconsidered to be “associated with the user,” as that term is usedherein.

In some embodiments, virtual agent 114 may be configured to perform oneor more actions based, at least in part, on user data such as contactinformation or scheduling information for a user. For example, ratherthan sending or receiving communications to other devices itself (e.g.,like an email or text message application), a virtual agent may directother applications to send one or more communications to another deviceon behalf of a user in response to interpreting user input or upon theoccurrence of a condition associated with a task the virtual agent isconfigured to perform.

In some embodiments, to facilitate an interaction with user data,virtual agent 114 may be configured to aggregate user data for aparticular user associated with the virtual agent. For example,scheduling information for a user may be present in multiple sourcesincluding a web-based calendar, a local application calendar, and a tasklist. Virtual agent 114 may be configured to aggregate the schedulinginformation across these multiple sources (and possibly others) and theaggregated user data may be stored for querying by the virtual agent. Byaggregating user data from multiple sources, the virtual agent may beable to quickly determine a more comprehensive view of the user's userdata without having to separately query different sources. It should beappreciated however, that not all embodiments require aggregation userdata. Rather, in some embodiments, the virtual agent may query multiplesources during a particular task (e.g., managing scheduling information)assigned to the virtual agent. In yet other embodiments, only some userdata may be aggregated while other user data is not aggregated.Additionally, user data other than scheduling data may alternatively beaggregated and scheduling data is provided merely as an example of thetype of data that may be aggregated.

The user data may be aggregated and stored in any suitable way. Forexample, at least some aggregated user data may be stored locally on auser's electronic device and/or the aggregated user data may be stored,at least in part, on one or more network-connected datastores accessibleto the user's virtual agent via one or more networks. In someembodiments, storage of user data “in the cloud” is preferred, as theuser data may then be made accessible to multiple electronic devicesused by the user and/or another user's virtual agent provided that theother user's virtual agent is given permission to access the user data.Data aggregated by a virtual agent for a particular user may be updatedperiodically and/or the user data may be updated in response to a userrequest. The particular manner in which the user data is updated is nota limitation of embodiments of the invention.

In some embodiments, a virtual agent associated with one user may invokea communication session with a virtual agent associated with anotheruser to perform one or more actions. The communication session betweenvirtual agents may be invoked in response to user input to perform theone or more actions in the foreground and/or the communication sessionbetween virtual agents may be invoked automatically without user inputto perform the one or more actions in the background, without userinput. In the disclosure herein, the user associated with the virtualagent that invokes the communication session is called the “sender” andthe user associated with the virtual agent that receives a communicationfrom the sender's virtual agent is called the “receiver.” Additionally,the electronic device of the sender is often referred to herein as the“sending device” and the electronic device of the receiver is oftenreferred to herein as the “receiving device.” It should be appreciatedhowever, that any electronic device may send and receive communicationsand this terminology does not limit the functionality of any particulardevice.

An exemplary process for invoking an agent communication session inresponse to user input is illustrated in FIG. 2. In act 210, user inputis received from a user of an electronic device. As discussed above, insome embodiments that include a speech interface, the user input mayinclude speech input that includes a request for the virtual agent toperform one or more actions that include participation by at least oneother virtual agent for another user. For example, a user (i.e., asender) may ask the virtual agent, “Where is John?” In response to thisquestion, the virtual agent may determine that the sender would likeinformation about a location of another user (i.e., the receiver) namedJohn, and the virtual agent may interact with user data (e.g., storedcontacts, scheduling information, etc.) in an attempt to determinecontact information for the intended receiver user, John.

In response to receiving user input, the process proceeds to act 210where it is determined whether a communication session with anothervirtual agent should be invoked. This determination may be based, atleast in part, on the received user input and the determination may bemade in any suitable way. In some embodiments, a determination ofwhether to communicate with another virtual agent is made by evaluatingthe content of the user input to identify one or more trigger terms forinvoking a communication session with a virtual agent associated withanother user. For example, trigger terms such as “where,” “home,” and“on my way,” used in connection with a name of a person may indicatethat the user's intent is to invoke a communication session related tolocation information. In response to receiving user input correspondingto the example discussed above (i.e., “Where is John”), the virtualagent for the sender may recognize the trigger term “where” followed bythe name of a person “John” and may determine that the sender wants toknow location information for John. The virtual agent may alsoincorporate other contextual data such as time of day, location, userhistory, or some combination to determine intent. If there are multiplelistings for “John” within contacts, the agent may look to which “John”the user communicates with most regularly, or typically from thatlocation or time of day. In another example, the sender may say “TellJohn I'm on my way and I should be there in twenty minutes.” In responseto receiving this input, the virtual agent may identify the trigger term“on my way” used in connection with a user named John and may determinethat the sender wants to inform John of the user's current location andan estimated time of arrival.

In some embodiments, information may be sent to an electronic device ofa user (i.e., a receiver) by sending a message (e.g., a text message)that includes this information to the receiver's electronic device. Forexample, in the above example, if John is not associated with a virtualagent (e.g., because his electronic device does not include a virtualagent application), John's electronic device may receive a text messagefrom the sender including the content “I'm on my way and he should bethere in twenty minutes.” However, if John's electronic device isassociated with a virtual agent, the incoming communication may beinterpreted by John's virtual agent to provide a richer user experience,as discussed in more detail below. Because the sender may not know apriori whether the receiver has a compatible virtual agent executing onthe receiver's device, the sender's device may provide an outgoingcommunication to the receiver's device to determine if a second agent ispresent on the receiver's device before sending the message. Based onthe response of the receiver's device, the first agent may interpret anappropriate type of message to send. If the receiver is not associatedwith a virtual agent, at least some of the content in a receivedcommunication from the sender may still be displayed on the receiver'sdevice (e.g., as a text message). Accordingly, some embodiments of theinvention allow for communications between electronic devices with orwithout virtual agents associated with the users of such devices, withusers not associated with virtual agents receiving conventional-typemessages (e.g., text message, instant message, email message, web-basedapplication, etc.) and users associated with virtual agents receivingthe content in a manner that may be interpreted by their virtual agentsto provide a rich user experience, including providing responsivecommunication with the sender's virtual agent.

Although the above examples describe communications related to locationinformation, other types of information may also be requested and/orshared using agent-to-agent communications in accordance withembodiments of the invention. For example, other types of informationthat may be requested or communicated include, but is not limited to,scheduling information, user content information (e.g., contactinformation or other user data), and any combination of locationinformation, scheduling information, and user content information. Insome embodiments, each type of information may be associated withtrigger words recognized by the virtual agent to inform the virtualagent of the user's intent. For example, trigger terms such as“schedule,” “when,” and “available” when used in connection with areceiver user's name may indicate that the action to be performedrelates to scheduling information and trigger terms such as “share” or“contact” may indicate that the action to be performed relates torequesting or providing user content information. It should beappreciated that these trigger terms are provided merely for exemplarypurposes and any suitable terms, phrases, or contextual data (e.g.,location, time of day behavior history, etc.) may be used by virtualagents in accordance with embodiments of the invention to determine theintent of the sender.

Returning to the process of FIG. 2, if it is determined in act 220 thatthe user does not intend to invoke a communication session with anothervirtual agent, the process proceeds to act 222 where an action isperformed based on the user input. For example, if the user input is,“Where is the movie theater?” the user's virtual agent may determinethat although the input includes the trigger term “where,” the term“movie theater” does not refer to another user. Accordingly, the virtualagent may determine that a communication session with another virtualagent is not an appropriate action to perform, and instead the virtualagent may perform another action such as a web search for movie theatersnear the location of the user, or some other suitable action.

If it is determined in act 220 that a communication session with avirtual agent for another user should be invoked, the process proceedsto act 230, where the content of an outgoing communication to thereceiver's virtual agent is determined. The virtual agent may determinethe content of the outgoing communication in any suitable way. In oneexample, if the user input is “Where is John?” the virtual agent maydetermine that the outgoing communication should include a request forthe location of the receiver John, and this request may be sent to anelectronic device using the virtual agent associated with John, asdiscussed in further detail below.

In some instances, the content of the an outgoing communication mayinclude a request that includes more than one type of information. Forexample, if the user input is “When is John expected to arrive at thegame?” the sender's virtual agent may understand that to determine anexpected arrival time of John at the game, the sender's virtual agentwill need to know the location of John, the location of “the game,” andhow long it will take John to travel between his current location andthe location of the game based, for example, on John's current speed. Inthis example, the sender's virtual agent may attempt to determine thesender's intent by identifying what the user likely means by one or moreterms in the user input. For example, the virtual agent may attempt toidentify the intended receiver John by interacting with the sender'suser data (e.g., the sender's contact information). If the virtual agentcannot identify the intended recipient, the virtual agent may prompt theuser to provide more information. The virtual agent may also attempt todiscover the intended meaning of “the game” based, at least in part, onthe sender's user data. For example, the virtual agent may interact withthe sender's scheduling information to determine whether there is ascheduled event corresponding to a type of game (e.g., a baseball game,a football game, etc.). Based on this investigation, the virtual agentmay determine the identity of “the game” and the corresponding locationof the game may also possibly be inferred by the virtual agent based onthe information in the scheduled event.

In some embodiments, the sender's virtual agent may not be able todetermine the meaning of certain terms in the user input, although avirtual agent for the receiver may be able to. In such instances, theoutgoing communication may include an indication that the sender'svirtual agent could not interpret certain terms, and a request to thereceiver's virtual agent to see if the receiver's virtual agent couldinterpret those terms. In some embodiments, all user input may betransmitted to the receiver's virtual agent and the receiver's virtualagent may provide confirmation (e.g., based on the receiver's user data)of an interpretation of the sender's virtual agent. In otherembodiments, only a portion of the user input may be transmitted to thereceiver's virtual agent and embodiments of the invention are notlimited by the amount of data communicated between virtual agents.

If contact information for the intended receiver is identified based onthe sender's user data, the virtual agent may create an outgoingcommunication based, at least in part, on the identified contactinformation. In some embodiments, if the virtual agent does not uniquelyidentify an intended receiver from the sender's user data, the virtualagent may prompt the user to provide more information to resolve theambiguity.

After determining suitable content to include in the outgoingcommunication, the process of FIG. 2 proceeds to act 240 where theoutgoing communication is sent to the receiving user's electronicdevice. In some embodiments, user data may include preferencesinformation for sending communications to one or more contacts in theuser's contact list and the outgoing communication may be sent to thereceiver's user device using the preferred communication method for thatparticular user. In the above example, the sender's user data mayindicate that the sender generally prefers to send communications to theintended receiver “John” using text messaging. Accordingly, in responseto determining that the intended receiver is John, the sender's virtualagent may create and send an outgoing communication as a text message toJohn's electronic device. Upon receiving the incoming text message, andprovided the receiving electronic device is associated with a virtualagent, the virtual agent may interpret the information in the textmessage to perform at least one action, as discussed in more detailbelow. If John's device is not associated with a virtual agent, thedevice may display the incoming text message in a conventional format.

In some embodiments, a virtual agent may learn user preferences for auser associated with the virtual agent. A virtual agent may learn userpreferences in any suitable way. For example, a virtual agent may learnuser preferences by tracking one or more behavior variables indicatingwhen a user prefers to send communications of a particular type.Behavioral variables that may be tracked for learning user preferencesmay include, but are not limited to, frequency of use, time of day, andday of the week. Additionally, user preferences may be specific toparticular intended receivers. In some embodiments, user preferences maybe stored as user data associated with a particular user, although theparticular manner in which user preferences are stored is not a limitingaspect of embodiments of the invention.

After sending the outgoing communication in act 240, the processproceeds to act 250 where optionally a response communication isreceived by the sending electronic device from the electronic device towhich the outgoing communication was sent. The response communicationmay include any suitable information corresponding to the outgoingcommunication sent to the receiving device. For example, the responsecommunication may include a confirmation that the outgoing communicationwas received by the receiving electronic device. The responsecommunication may also include information in response to one or morerequests included in the outgoing communication (e.g., the location ofthe receiving user in response to a request for the receiving user'slocation). The response communication may also include one or morerequests from the receiving user's virtual agent to provide additionalinformation prior to performing the one or more actions specified in therequest(s) in the outgoing communication. Communication may continuebetween the virtual agents for the sender and the receiver until theaction(s) have been performed or one of the users has cancelled thecommunication.

Although communication between virtual agents may not requireinteraction from one or both of the users to perform an action (e.g.,scheduling an appointment based on the users' calendars), in someembodiments one or both of the users may be prompted to confirm anaction prior to actually performing the action. For example, providinginformation that may be considered private information (e.g., a user'slocation) may, in some embodiments, require user confirmation prior toproviding the information to another user. Restrictions on sharinginformation between virtual assistants may be implemented in anysuitable way and embodiments of the invention are not limited in thisrespect.

In some embodiments, one or more tasks may be delegated to a virtualagent such that communication between the virtual agent of one user andthe virtual agent of one or more other users occurs in the backgroundwith or without intervening input from the users associated with thevirtual agents. An exemplary process for managing a task withoutrequiring user input to begin the process is illustrated in FIG. 3. Inact 310 the agent monitors user data to determine whether a conditionassociated with the assigned task has occurred.

In one illustrative example, the task assigned to the virtual agent maybe to manage a user's events and appointments included in schedulinginformation for the user, and the condition the virtual agent may beconfigured to monitor may be whether the user is likely to be late for ascheduled event. The virtual agent may make this determination in anysuitable way. For example, the virtual agent associated with a firstuser may interact with user data for the first user to determine thatthe first user has a lunch meeting scheduled with a second user at 12:00pm at a particular restaurant. The virtual agent may also determine thefirst user's location using, for example, a location sensor included inthe first user's electronic device. As the time approaches for ascheduled event (e.g., 15 minutes before the scheduled event), thevirtual agent may compare the location of the first user and thelocation of the restaurant to determine whether it is likely that thefirst user will arrive at the restaurant on time for the scheduledmeeting. This determination may be made in any suitable way andembodiments of the invention are not limited in the particular way avirtual agent determines an estimated travel time between two locations.

In response to determining that a condition has occurred (e.g.,determining that the user is unlikely to be available for a scheduledevent), the process proceeds to act 312 where it is determined whetherthe user should be alerted to the occurrence of the condition. Thedetermination of whether to alert the user may be made in any suitableway including basing the determination at least in part, on the type oftask delegated to the virtual agent. In the example described above,when the virtual agent determines that the user is going to be late fora scheduled meeting, the virtual agent may alert the user that they arelikely to be late to the meeting and the process proceeds to act 314where the user may be prompted whether an outgoing communication shouldbe sent to the second user's device to inform them that the first userwill be late to the scheduled meeting. As described further below, othertasks delegated to a virtual agent may be performed without interactionor confirmation from the user and embodiments are not limited in thisrespect.

In response to the user responding to an alert in act 314 or if it isdetermined in act 312 that the type of task delegated to the virtualagent does not require a user alert, the process proceeds to act 316where it is determined whether at least one other user should be alertedto the occurrence of the condition. If it is determined in act 316 thatan outgoing communication should be send to at least one other user, theprocess proceeds to act 318 where a communication is sent to the atleast one other agent.

In the example above, in response to determining that the first userwill be late to the scheduled meeting, the virtual agent may send anoutgoing communication to the electronic device of the second user toinform the second user that the first user will be late. In someembodiments, the outgoing communication may include other information aswell, including, but not limited to, a current location of the firstuser, and information about an estimated time of arrival of the firstuser to the scheduled meeting. In some embodiments, the virtual agent ofthe first user and the virtual agent of the second user may continue tocommunicate information about the first user's location and/or thesecond user's location to provide one or more real-time updates of anestimated time of arrival of the users for the scheduled meeting. Forexample, if the virtual agent for the first user determines that thefirst user is likely to be thirty minutes late to the scheduled meeting,the first user's virtual agent may send a follow up communication to thevirtual agent for the second user when the first user arrives at thescheduled meeting place and/or shortly before the first user is expectedto arrive.

Once received, the virtual agent associated with the second user mayinterpret the information in the outgoing communication to alert thesecond user of the occurrence of the condition. As described above, thereceived communication may include additional information such as a linkto a map application identifying the first user's current location. Inresponse to receiving the communication from the first user, the seconduser's virtual agent may interpret the communication to display a map onthe second user's electronic device showing the first user's currentlocation and/or the estimated arrival time. As discussed above, if thesecond user's electronic device does not include a compatible virtualagent capable of interpreting the received communication to, forexample, display a map of the first user's location, the second user maystill be alerted using conventional communication applications such astext-based application (e.g., email or text messaging application).

In some embodiments, a virtual agent may be assigned a task to monitoran event that does not require alerting the user in response to theoccurrence of a particular condition. When an electronic device for auser is put into a particular mode (e.g., silent mode or vibrate mode)or if the electronic device is turned off, a virtual agent associatedwith the user may be assigned the task of monitoring incomingcommunication to the device and sending a response communication to thesender of the incoming message that the user is currently unavailable.In some embodiments of the invention, the response communication mayinclude additional information that may be interpreted by a virtualagent associated with the user who sent the incoming communication. Forexample, the response message may include information describing whenthe receiving user will be available or the response message may includeinformation to send the communication using a different format (e.g.,text message rather than telephone call).

In some embodiments, a virtual assistant may change the behavior of anelectronic device based on interactions with the user data for the userof the electronic device. For example, the virtual assistant maydetermine based on the user's scheduling information that the user isscheduled to be in a meeting from 1-2 pm. When the virtual agentdetermines that the user is in the meeting (e.g., because it is 1 pm)the virtual agent may instruct the electronic device to automaticallyenter a silent or vibrate mode, thereby preventing the electronic devicefrom disturbing others in the meeting. The virtual agent may alsodetermine when the meeting has ended (e.g., because it is 2 pm) and thevirtual agent may instruct the electronic device to exit silent/vibratemode. In some embodiments, prior to exiting silent/vibrate mode, theuser may be prompted to confirm whether exiting silent/vibrate mode isdesired.

An exemplary process for monitoring incoming communication for anelectronic device of a user in accordance with some embodiments of theinvention is illustrated in FIG. 4. In act 410, an incomingcommunication, such as a text message or a telephone call, is receivedby an electronic device of a user. The process then proceeds to act 412where it is determined by the virtual agent associated with thereceiving electronic device whether the user is currently available. Adetermination of whether a user is currently available may be made inany suitable way. For example, if the electronic device is currently ina particular mode such as silent mode or vibrate mode, as discussedabove, the virtual agent may determine that the user is unavailable andthe process may proceed to act 414 where an outgoing communication issent to the electronic device that sent the incoming communication.

Rather than just indicating that the user is unavailable, in someembodiments, the outgoing communication may include additionalinformation to inform the user who sent the incoming message when theunavailable user may be available to communicate. For example, inresponse to determining that a user is unavailable to receive anincoming communication, the user's virtual agent may interact with userdata (e.g., scheduling information) for the user to determine when theuser will be next available to communicate. After consulting the userdata, the virtual agent may include information in the outgoing messageindicating one or more time preferences for rescheduling thecommunication. By proposing a time to reschedule the communication, theuser who sent the incoming communication may be able to select a timethat is convenient for both users. After the outgoing communication issent, the process proceeds to act 316 where the virtual agents for thetwo users may send one or more further communications to negotiate atime that is mutually acceptable to both users based on their schedulinginformation.

In some embodiments, a user may configure a virtual agent to respond tocertain incoming messages in a different way than other incomingmessages. For example, if the incoming message is from a user that isrecognized by the virtual agent as one of the receiving user's contacts,the virtual agent may be instructed to communicate with the sendinguser's virtual agent to reschedule the communication at a mutuallyacceptable time. However, if the incoming message is from a user that isnot in the receiving user's contact the virtual agent may be instructednot to reschedule the communication. Preferences for modifying thecommunication behaviors of virtual agents in accordance with someembodiments may be implemented in any suitable way and embodiments ofthe invention are not limited in this respect.

In some embodiments, when an electronic device receives an incomingcommunication from a virtual agent, a virtual agent associated with theuser of the receiving device may interpret the information in theincoming communication to perform one or more actions. An exemplaryprocess for processing an incoming communication received by anelectronic device in accordance with some embodiments of the inventionis illustrated in FIG. 5. In act 510, a communication from a virtualagent of a first user is received by an electronic device of a seconduser. The communication may be received in any format the electronicdevice is capable of receiving incoming communications. For example, thecommunication may formatted as, but is not limited to, a text-basedmessage, an instant message, a telephone call, or a video chat session.If the receiving device is associated with a virtual agent, the virtualagent is configured to perform at least one action based, at least inpart, on the content of the information in the received communication.

The virtual agent may interpret the received communication in anysuitable way to determine the content of the communication andembodiments of the invention are not limited in this respect. Forexample, when the incoming message includes text, the virtual agent maydetermine whether any of the text corresponds to one or more triggerwords that indicate the type of request included in the communication.The trigger words may be the same or different than the trigger wordsdiscussed above in connection with invoking an agent communicationsession and determining the content of an outgoing communication. Bydetermining whether the incoming communication includes particulartrigger words, the virtual agent may determine how to proceed withprocessing the request in the incoming communication. For example, if atrigger word related to location information is included in the incominginformation, the virtual agent may perform one or more actions relatedto location-based requests, including, as described below, prompting theuser for confirmation to share the user's location. Other types ofrequests include, but are not limited to, scheduling requests, usercontent exchange requests, and requests that include multiple types ofinformation (e.g., location information and scheduling information).

It should be appreciated that identifying a type of incomingcommunication based on trigger words in the incoming communication isonly one way a virtual agent may determine information about the type ofcontent in an incoming communication and other ways are alsocontemplated. For example, in one implementation communications sentbetween virtual agents may be associated with metadata that provide anindication of the type of content in the communications and virtualagents may be able to determine the type of content based, at least inpart, on the metadata associated with a communication.

In response to determining the content of the incoming communication,the process proceeds to act 514 where it is determined whether userinteraction is required to act on one or more of the requests in theincoming communication. If it is determined that user interaction isrequired prior to acting on a request in the incoming communication, theprocess proceeds to act 516 where the user is prompted to provide userinput to continue. An example where user input may be required is if theincoming communication includes a request for location information of auser. For example, if the incoming communication includes “where areyou?” the virtual agent may determine that the user who sent theincoming message wants to know the receiving user's location. Some usersmay consider their location as private information that should notgenerally be shared with other users. Accordingly, in response todetermining that the incoming communication includes a request for theuser's location, the receiving user's virtual agent may display on auser interface of the electronic device an indication to the user thatthe sending user wants to know the receiving user's location and toconfirm that this information may be shared with the sending user.Alternatively, or in addition to displaying a prompt on a userinterface, the electronic device may provide the prompt in some otherform including speech output.

Incoming communication other than requests for location information mayalso require user interaction. For example, an incoming communicationfrom a virtual agent from a user may include a request to add contactinformation to the receiving user's contacts and in response todetermining that the request is to modify user data for the receivinguser, the receiving user's virtual agent may prompt the user to indicatethat the sending user would like to add contact information to thereceiving user's contacts. In response to receiving the prompt, thereceiving user may confirm or dismiss the request to add the contactinformation included in the incoming communication.

In some embodiments, a user may be able to set permission and privacypermissions that the user's virtual agent may consult to determinewhether user interaction is required for particular types of requestsand/or what information may be shared with particular users or all userswho request the information. In some embodiments, at least somepermission or privacy permissions may be set by an application designerfor the virtual agent and the user may not be able to change thesepermissions. For example, the application designer for the virtual agentmay determine that user prompts are always required for sharing locationinformation, but permissions related to displaying user prompts forsharing user content data are user-configurable. It should beappreciated that these examples are provided merely for illustrativepurposes and do not limit embodiments of the invention.

Returning to FIG. 5, if it is determined in act 514 that userinteraction is not required or in response to receiving user input froma prompt presented in act 516, the process proceeds to act 518 where oneor more actions are performed by the virtual agent to respond to therequest(s) included in the incoming communication. For example, if theincoming communication included “Where are you?” and the receiving userhas given permission to share the user's location, the virtual agent mayquery the location sensor of the electronic device to determine thelocation of the user. The process may then proceed to act 520 where aresponse communication is sent to the virtual agent that sent theincoming communication. In a request for a user's location, the responsecommunication may include, for example, a link to a web page for a mapapplication showing the receiving user's location. In response toreceiving the response communication, the agent that issued the requestfor the location information may display on the requesting user'sdevice, a map showing the location of the other user. This may beaccomplished, for example, by the requesting user's virtual agentinstructing a web browser application to navigate to the link in theresponse communication.

In some embodiments, the incoming communication may include multiplerequests and the virtual agent of the receiving user may performmultiple actions in accordance with the requests. For example, theincoming communication may include, “Tell Dave that the meeting is goingto be delayed and let me know when he reads it.” In response to thisincoming communication, the virtual agent of the receiving user (i.e.,Dave) is instructed to perform two actions. The first action is toinstruct the receiving user that a scheduled meeting will be delayed andthe second action is to monitor the behavior of the receiving user todetermine when the receiving user has read the message about themessaging being delayed. In response to determining that the receivinguser has accessed the message, the receiving user's virtual agent maysend a response message to the requesting virtual agent to fulfill thesecond request in the incoming communication. Accordingly, in thisexample, the virtual agent of a first user can control the behavior ofvirtual agent of a second user to perform an action (in this case,monitoring the receiving user's behavior) on behalf of the first user.

Another example of processing an incoming communication that includesmultiple requests is an incoming communication such as “Has my wife leftthe office yet? Please let me know when she will be home and let me knowwhen she is five minutes away.” This incoming communication includesthree actions that the virtual agent associated with the user's wifemust perform. In response to receiving this incoming communication, thewife's virtual agent will determine the wife's location (e.g., byquerying a location sensor on the wife's electronic device) to determinewhether she is at a location corresponding to her office. Presuming thatthe user's wife agrees to share her location, the wife's virtual agentmay inform the user's virtual agent that his wife has left the officeand is on her way home. The user's virtual agent may then present thisinformation on the user's electronic device. In some embodiments, thisresponse message may also include information about the wife's currentlocation that may be used by the user's virtual agent to display herlocation on a map.

The second action to perform is to estimate when the wife will arrivehome. The wife's current location may also be used to determine anestimated time of arrival when she is expected home. This determinationmay be made in any suitable way and the determination may be made underthe direction of the wife's virtual agent or the user's virtual agent.For example, the determination may include various factors including,but not limited to, how long it usually takes the wife to drive homefrom her current location, current traffic conditions, and the speedlimit of the roads between the wife's current location and home.

The third action in the incoming communication is for the wife's virtualagent to notify the user's virtual agent when the wife is five minutesfrom home. In some embodiments, the wife's virtual agent may provideperiodic updates to the user's virtual agent describing the wife'scurrent location. In other embodiments, the wife's virtual agent maymerely monitor the wife's progress and estimate when she is five minutesfrom home. When this condition is satisfied, the wife's virtual agentmay then send a communication to the user's agent that she is almosthome.

In some embodiments agent-to-agent communication in accordance with someembodiments of the invention may be used to facilitate tasks requiringcoordination between multiple virtual agents for different users. Forexample, a user may want to have dinner with his friends Megan and Benat a time that is convenient for all three users. Rather thancommunicating using individual requests to each of Megan and Ben, theuser may instruct the user's virtual agent as follows: “Please scheduledinner with Megan and Ben if they are available for dinner Saturdayevening.” In response, the user's virtual agent may determine thecontact information for Megan and Ben based on the user's contactinformation and send outgoing communications to the virtual agents forMegan and Ben to determine based, on each of their stored user data, ifand when they would be available for dinner on Saturday evening. In theoutgoing communication, the user's virtual agent may include one or moresuggested times based on the user's scheduling information that thevirtual agent may access prior to sending the outgoing communications.In response to sending the outgoing communications to the virtual agentsfor Megan and Ben, the user's virtual agent may receive responsecommunications from the virtual agents for Megan and Ben indicatingtheir availability and the virtual agents may continue to negotiate atime that is mutually acceptable to all of the users. After anacceptable time has been determined, each of the users' virtual agentsmay update the corresponding user's scheduling information and send anotification to the users that the dinner has been scheduled.

As should be appreciated from the foregoing, embodiments of theinvention that provide agent-to-agent communication in association withaccess to user data and permission and privacy preferences allows forfunctionality that conventional virtual agent implementations do notcontemplate and typically cannot achieve. The examples provided hereinare discussed merely as examples of functionality provided byembodiments of the invention and any other functionality that maybenefit from coordination between at least two virtual agents are alsopossible.
